英文摘要 | PURPOSE:To set the band-gap energy on the side of GaAs lower than that on the side of AlGaLnP and hence lower operating voltage by providing a P-GaInP buffer layer between a P-GaAs contact layer and a P-AlGaInP cladding layer. CONSTITUTION:There are provided on an n-GaAs substrate 1 an n-Al0.25Ga0.25 In0.5P cladding 2, a non-doped Ga0.5In0.5P active layer 3, a p-Al0.25Ga0.25P cladding 4, an n-GaAs current blocking layer 5, a p-Ga0.5In0.5P buffer 6, a low temperature grown p-Ga0.5In0.4P buffer 7, a p-GaAs contact 8, a bridge 9, and n, p side electrodes 10, 1 With the growth temperature of the layers 1-6 being 650 deg.C and with a V/III group ratio being 400, the low temperature grown buffer 7 is grown with its temperature being changed gradually a range of 650 deg.C-600 deg.C. For film thickness, the layer 6 is of 0.05mum and the low temperature grown buffer 7 is of about 0.05 mum. With such configuration, bands of the layers 4, 6, 7, and 8 are gradually changed and hereby potential barriers on the side of valence electron bands are moderated. Thus, low voltage operation is assured. Provided growth temperature on the side in contact with GaAs is set lower than that on the side of an AlGaInP side, a low resistance ratio is achieved. |
